3 Claims;

1 This invention relates to a husking device. More specifically; it relates to a shelled-corn saving and recovering device for use with husking rolls. In conventional husking means for ear gear 16 which meshes with and drives a'bevelgear corn after it has been snapped from the stalks, 5 H onthe vertical shaft 14. It is to be understood rolls are usually utilized for gripping the shucks that any type of conventional mechanism may and removing them from the ears. The same be utilized for driving the husking rolls, ear-fortype of husking device is usually utilized whether warding means, and the movingelements-of the the corn is snapped from standing stalks by a shelled-corn saving device. A housing-structure traveling picker or removed from out stalks either is illustrated including a deflector wall i8" which by a traveling machine or by a stationary snapper projects adjacent the upper husking roll It to and husker. When the corn is dry, there is conassure the-delivery of ear corn to the husking siderable shelling particularly around th butt position between the rolls.

This formation in'g downwardly in the same-direction, the rolls rotating in opposite angular directions. A longitudinal shaft l5 is indicated as carrying a bevel has a particular function, as will be hereinafter described. a

The shaft 28 extends through the end member 21. A gear 3|, illustrated as being mounted on the end of said shaft, shows diagrammatically a means of driving a second shaft 32 by means of a drive sprocket 33mounted thereon. By dotted lines in Figure 1a means of driving the shaft 28 from the shaft I is diagrammatically illustrated. Said shaft may be driven by a sprocket 34 on the sprockets being connected by a drive chain 36.

pivotally mounted on a shaft 38 at substantially the same height as the husking rolls. Said elements are spaced apart and extend downwardly that the elements 30 have freedom between the rotating disks. Said elements extend outwardly over the upper edge of the adjustable wall 23, said wall having a curved abutment 38' on which the elments rest.

A grain-conveying auger 39 is rotatably mounted on the shaft 32, previously described, being fitted in the trough-like portion of the grainreceiving chamber formed by the cylindrical wall 2 I. Said auger serves as conveying means to discharge the shelled grain to a suitable receptacle or conveying means.

In the operation of the structure as above described, the ears-and perhaps shelled grain and other trash-are dumped onto the husking roll in being carried therealong by the conveying chain II. The grain drops through and around the rollers and the husks are removed and passed between the rolls. Considerable corn may also be removed from the ears by the husking rolls as it is difiicult to devise rolls which are aggressive enough to remove the husks without shelling a considerable amount of corn. The husks and other material are engaged by the smooth contour portions A of the notched disks which raise and shake the husks without an aggressive forwarding motion. The shape of the notches, as previously described, is such that as soon as the curved surface A passes under the material, raising it vertically, the material may drop because of the radial edge B of the projections. This gives a shaking action along with the forwarding action. A further shaking action is obtained by the lifting of the elements 31 by the cams 30. This action is such that it may be termed as a shaker grid with the elements being oscillated by the cams. For different conditions of operation, the wall 23 may be adjusted with respect to the wall 22 to vary the position of the abutment 38 on which the shaker elements rest, thereby determining the amount of oscillation of said elements by the cams 30.

The husks and other material moved by the disks 29 generally in the direction of rotation of the projections on the disks and assisted by the shaking of the elements 3'l, pass outwardly and into the discharge chute 25 dropping out of the device.

It is to be understood that applicant has shown and described only a preferred embodiment of his improved shelled-corn saving device for corn husking mechanisms, and that he claims as his invention all modifications falling within the scope of the appended claims.

A plurality of rod-like shaker elements 31 are and outwardly between the notched disks 29., The spacing of the disks by the cams 30 is such shaft I5 and a sprocket 35 on the shaft 28, said 7 What is claimed is:

A grain saving means for a corn huskin machine comprising in combination with husking rolls through which husks and shelled grain are delivered in a downward direction during operation, a shaft located beneath said rolls, a pluralityof spaced trash'and husk agitating and forwarding elements mounted on said shaft, a plurality of rod-like elements extending downwardly between said elements above said shaft and below the upper portions of the said elef ments, means for pivotally supporting the rodlike elements at one end, means for engaging,

lifting and thereby vibrating said elements, and shelled-corn receiving means below said elements,

said means including a receptacle having an upwardly extending wall on which the free ends of the rod-like elements rest when not engaged by said vibrating means.

2. Grain saving means for a corn husking machine comprising in combination with a pair of substantially horizontal husking rolls through which husks and shelled grain are delivered in a downward direction during operation, a shaft located beneath said rolls, a plurality of spaced notched disks mounted on said shaft, a plurality of loosely mounted grid forming elements extending downwardly between said disks above said shaft and below the upper portions of the disks, means for pivotally supporting said elements at one end, cams on said shaft between the disks for vibrating said elements, and shelledcorn receiving means below said shaker elements, said means including a receptacle having an upwardly extending adjustable wall on which the grid-forming elements abut, the adjustable wall providing means for varying lift on the grid forming elements by the cams.

3. In combination with a pair of husking rolls through which husks and shelled grain are delivered in a downward direction during operation, a substantially horizontal shaft located beneath said rolls, a plurality of spaced notched disks mounted on said shaft, a plurality of shaker ele--' ments extending downwardly between said disks above said shaft and below the upper portions .of the disks, means for pivotally supporting said REFERENCES CITED The following references are of record in the file of this patent:
